XD has long history to manufacture rectifier transformer with advanced technique, various specifications,
and stable and reliable quality. Early in 1970s, the company firstly manufactured the large direct-drop
rectifier transformer to fill the blank in the field in China. In 1980s, XD cooperated with many famous
manufacturers at abroad and absorbed the advanced technology and technique widely. It produced the high
quality of the products reaching to the international advanced level for the customers both at home and at
abroad. In 1996, the first set of 220 kV direct-drop rectifier transformer in China, which was made by XD,
was put into operation successfully at Yunnan Aluminum Plant, and the technical performance and the
reliability of the product can be competed with those of foreign advanced products of the same kind.
